Apple Ads brings this same approach to advertising, helping people find exactly what they're looking for and helping advertisers grow their businesses. Our technology powers ads and sponsorships across Apple Services, including the App Store, Apple News, Apple Maps, MLS, and F1. Everything we do is designed for trust, connection, and impact: we respect user privacy, integrate advertising thoughtfully into the experience, and deliver value for advertisers of all sizes - from small app developers to big global brands. Because when advertising is done right, it benefits everyone.\nYou will join a team of world-class engineers with an appetite for applying leading-edge technologies to deliver extraordinary experiences to our customers, and collaborate closely with the business to deliver relevant data and insight that informs our strategy and decisions.\nYou should have 1-4 years of experience in software engineering roles, ideally within the ads or media space. You will have a strong understanding of scalable approaches and thrive working in Agile environments. The ability to be a good, standout colleague under tight deadline constraints is key to success. We will calibrate the level and scope to your experience.\nDescription\nAt Apple Ads, we are building the next generation of privacy-focused advertising capabilities. As part of the data organization, we work at the cutting edge of data engineering, machine learning, and privacy at Apple's scale. We are constantly developing data products to provide amazing user experiences and to drive value for developers and publishers. As a member of the Data Org, you will:\n- Engineer secure, scalable data and machine learning systems across real-time, near-real-time, and batch execution contexts using Spark, Kafka, Iceberg, and beyond\n- Own the design and delivery of core components - from pipeline architecture to ML model development, training, and deployment - including support for privacy-preserving, mission-critical infrastructure\n- Drive reliability, performance, and efficiency improvements across your systems, including schema changes, backfills, and the experimentation and testing infrastructure (e.g. A/B testing) needed to validate them\n- Apply a strong understanding of the intersection between business, analytics, and engineering, with a proactive focus on reusable, efficient solutions\n- Use LLMs and AI coding agents (e.g. Claude, Gemini) daily to accelerate implementation, testing, and debugging - continually validating every result for correctness, privacy, and cost\n- Collaborate with a team of world-class engineers and product managers; grow through code and design reviews, and mentor others as you gain seniority\n- Contribute to on-call, monitoring, and continuous reliability and efficiency improvements; more senior engineers help lead incident response and root-cause analysis\n- Work effectively in a rapidly changing, sprint-based Agile environment, and contribute to a culture that emphasizes reliability, resiliency, extensibility, scalability, and productivity. We are one team, nurturing each other's growth and supporting each other in delivering for our customers and Apple\nMinimum Qualifications\n1+ years of industry experience building scalable data pipelines and machine learning systems, or other distributed software, at scale\nStrong computer science and software engineering fundamentals\nProficiency in modern programming languages such as Rust, Python, Java, or Scala\nExperience with distributed systems and data processing technologies (e.g. Spark, Kafka, Flink)\nExperience building and scaling systems on premise and in the cloud\nSolid understanding of data structures, algorithms, and system design principles\nAbility to communicate effectively with cross-functional technical and non-technical teams\nHands-on experience using LLMs (e.g. Claude, Gemini) in daily engineering work - for code generation, review, debugging, test writing, agentic loops, and evaluation systems- to continually improve software engineering skills and velocity\nExcellent collaborative skills\nBS/MS in Computer Science, Software Engineering, Distributed Systems, or a related field\nPreferred Qualifications\nExperience with NoSQL datastores (e.g. Cassandra, Keyspaces, ElastiCache)\nExperience with lakehouse and Iceberg table formats\nExperience with anomaly detection\nExperience with A/B experimentation frameworks\nHistory of driving reliability, efficiency, or cost improvements, and mentoring other engineers\nComfortable working in a rapidly changing environment with ambiguous requirements\nPrior experience in the advertising industry is a huge plus","description_format":"text","description_chars":4696,"description_truncated":false,"requirements":{"experience_years_min":1,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Operating Systems","Laptops","Smartwatches & Fitness Trackers","Tablets"],"lifecycle":[{"event":"open","at":"2026-10-12T19:41:51Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 6,350 · green card filings: 37","filings_12m":6350,"filings_prev_12m":6527,"green_card_filings_12m":37,"median_offered_wage_usd":177355,"route":null,"cap_exempt":false,"checked_at":"2026-10-03T21:08:04+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":239}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":138,"reasons":["conf:1","win:early","comp:junior,brand"],"computed_at":"2026-10-13T05:21:24Z"},"pay":null,"html_url":"https://alion.io/job/apple-data-engineer-data-products-apple-ads","json_url":"https://alion.io/job/apple-data-engineer-data-products-apple-ads.json","meta":{"generated_at":"2026-10-13T05:21:24Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":8257,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":12},"rest":"https://alion.io/mcp/rest/get_company?id=12"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fapple-data-engineer-data-products-apple-ads"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fapple-data-engineer-data-products-apple-ads"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fapple-data-engineer-data-products-apple-ads"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/apple-data-engineer-data-products-apple-ads\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fapple-data-engineer-data-products-apple-ads"}]}
